Specification of Letters Patent.

Patented Dec. 5, 1905.

Application filed May 6', 1905. Serial No. 259,161.

i any angle in the directionof the dra t and held in the position set against displacement. The construction and advantages of my invention will be explained in detail'herein after and illustrated in the accompanying drawings, in which v I Figure 1 is a side view of a'plow, showing my improvements in position thereon; Fig.

2, a rear view of the ploW-fr'amewith theattachment in osition, and Fig. 3 a detail view of one of t e disks and its mounting.

In the drawings similar reference characters indicate corresponding parts throughout the several views My invention is applied to a plow-frame consisting of two parallel horizontal lowbeams A, having laterally-extending a es B, on which are journaled traction-wheels C, the two beams bein connected by means of an arch D, designe .to straddle the 'row of growing plants, and to said arch is secured the hande E.

F represents the disks, which'arerevolw' bly mounted between the forked ends 9 ofuprights The upper ends of u rights G are adapted to be inserted throug holes in the beams A and secured in place by means of nuts I-I, fitting screw-threads on the ex- 1 treme ends of said uprights.

I represents a serrated annular shoulder made integral with the uprights G, that are adapted ,to engage serrations J on the under side of the beam and hold the upright in position to keep the disk F mounted therein from turning in a horizontal plane, it being also understood that. this structure also admits of securing the disk at any desired an- 'gle relative to the draft.

As shown in the drawings, the disk may be made concavo-convex in cross-section, though other forms may be employed, if desired, without altering the spirit of my invention, which consists, essentially, of the construction of the revoluble disks and the construction by which the disks may be set at any angle to the draft desired by the op erator. It will also be understood that my invention may be used equally as well for cultivating growing plants, a weeder, or for digging the plants, especially onions, by arranging the angle of the disks as hereinbefore described.

Having thus described my invention, what I claim is I A device of the character described, consisting of two parallel beams, a lateral-extending axle on each beam, traction-wheels journaled on said axles, an arch secured to said beams, a forked upright secured to each beam, a concavo-convex disk revolubly mounted 1n each uprlght, an annular ser-- rated shoulder on each upright, and serrations on the under side of the beams to engage the serrations on said shoulder, substantially as shown'and described.

In witness whereof I have hereunto set my hand in presence of two subscribing 'witnesses.

WILLIAM H. SUFFIELD.
